摘要： The invention relates to a method of preparation of a FGM shape with a first surface comprising up to 100% of a first material and a second surface comprising up to 00% of a second material using sintering, preferably spark plasma sintering (SPS). The method comprises the steps of: selecting the first material with a first sintering temperature and a first melting temperature and the second material with a second sintering temperature and a second melting temperature, wherein the first melting temperature is higher than the second melting temperature,loading a first layer of the first material in a die, adding at least one intermediate layer on the first layer, the intermediate layer comprising a mix of the first and second material creating an intermediate graded composite region and loading a second layer of the second material on the at least one intermediate layer. The invention is characterized in that an electrically insulating layer is added on the second layer of the second material which enforces the current from the sintering process to flow only through the die and not through the second layer of the FGM-shape.

摘要： The invention concerns a method for manufacturing a ceramic material with pseudo-isotropic microstructure. The method for tailoring the microstructure for manufacturing of sintered ceramic components involves a spark plasma sintering (SPS) process. By performing the SPS process in at least two steps it is possible to separate densification from grain growth. An initial sintering step at a first temperature and a first pressure, followed by a controlled grain growth step at a higher temperature and lower pressure makes it possible to manufacture ceramic components with controlled microstructure and improved mechanical properties.
